OIL-WELL DERRICK-HEAD GONSZR UQIION.

Application filed July 5, 1923. Serial No. 649,745.

This invention relates to improvementsin derrick constructions, havingfor an object to provide a novel and strong head construction forderricks employed in the drillingof oil, gas, and artesian wells, suchas is illus; trated and claimed in my copending United; tatesapplication for Letters Patent, serial numbered 649,746, wherein theinvention en bodies means for effectually withstanding the stress andweight applied thereto with installation and operation ofthe welldrilling rig.

It is likewise an object of the invention to provide a derrick headconstruction wherein the supporting beams and bolsters are arranged andsupported in a manner to'prevent their collapse, as bytwisting orhnckling and yet, to render the operation of as semblys'imple andreadily effected.

' Other objects will be. in part obvious and r in part pointed 0. 11hereinafter.

I orde th t th n ention and its mo e of operation may be readilyunderstood'by P rsons skilled intl I .h rini h omr ny e l us ra e dra ins. in he detailed following description based thereon, set out onepossible embodiment of; the same.

Figure 4: is a detail perspective of one of the supporting sections. 7

Having more particular reference to. the drawings, in connection, withwhich like characters of reference will designate corresponding partsthroughout, the improved head construction is especially adapted for useupon oil well rig derricks, whereinthe derrick includes a pluralityofrectangularly arranged leg sections indicated herein the numeral 1,eachof said legsections. having positioned upon its upper end andSupported thereon, short supporting sections 2;whi ch as will be noted,are of cross sectional size greater than the leg sections, 1, The sup.-porting sections 2 are secured in longitudinal alignment with the upperends of the leg sectio'ns l bylneans of angle bracket plates .3 boltedto adjacent portions of the leg sections and supporting sections 2 asindicated at fl and having transversely disposed corner slots 5 formedin the opposite ends thereof whereby to permit the connect-ion ofsectional adjustable struts 6 thereto, in the manner indicated in theFigure 1 (this matter being illust-rated and claimed in my cope'n'di'ngparent application) v The upper ends of each of the supporting sectionsQare shouldered, as'indicat'ed at .7,

while. the upper extremities of'the reduced portionsthereof are providedwith right angularly disposed shouldered seats 8.-

v Oppositely arranged transversely disposed bolsters 9 are seated in theopposed shoulders 7 formed upon the, upper ends of thesupportingsections 2, as shown in the Figure 1, while thelowersideopposite end portions of the supporting ;beams 10' are seated in theshouldered S MS 8 formed upon the. reduced portions. ofs'aid supportingsectionsQ, as 'is also shown inthe Figures 1 and 3. In this connection,it isjto be noted that thebolsters 9 and the opposed supporting beams 10are arranged in paralle re at nsh p PO11 t 9.1 9 51% sides. f he derr kand, o firm y nterconnect; the same and to relatively brace hemkb ieeinsbars or; tim rslll a ngaged at their lower side opposite end portionswith the ledges formed by the positioning of the Sl lpportingbeams: 1 0within the. shouldered 1 seats, 8 asshowniin the Figure 3, whereupon tierodsl2 are passed thIfQlighftliQ opposite end portions otthe supportingbeams 10 and have; the nuts upontheir' opposite ends: tightened so astoefi'ectthe clamping engagement of; the'severalbracing timbers 11 intheir seated positions upon th upper ends. or ledges provided pon thefree end of the reduced portions of the supportin sections 2. Thus,liability of lateral disp aceinent of the bracing timbers 11 withrespect to the supporting sections 2 and the bolsters and supportingbeams 9 and 10 will be prevented.

To'efiect further bracing of the head construction of the derrick, anglebracket plates 13 are arranged dver the upper extremities ofthe outersides of the supporting sections e supporting beams 10, as

treini-ti s of t Shown. the Figuresfl, andfB pthese angle plates beingsecurely bolted in position, as indicated at 14 v and having cornerslots 15 formed transversely. of the intermediate portions thereof,adapted to be engaged by the upper or tree hooked extremities of thesectional adjustable struts (3, which struts, as will be noted, aredisposed diagonally of and between the short sections 2. lhus, bytightening the turnbuckles 6 oi the struts 6, proper tension may beapplied thereto for ellectually bracing the derrick head consl ruction'.

Bearing surfaces are provided upon the upper sides oi? the severalsupporting beams lOby arranging L-shaped irons l6 thereon, as shown inthe Figure 1.

lVith my improved derrick head construction, I am enabled to provide thederrick with means which will effectually support and successfullywithstand the greatstress to which devices of this character aresubjected with installation and operation ot a well drilling rig. Byproper adjustment of the sectional adjustable struts 6 through themedium of the turnbuckles 6 proper tension may be had throughout thehead construction whereby to avoid any liability of any twisting orbuckling of the same.

Furthermore, by reason of the novel arrangement of the bolsters and thesupporting beams which are positioned and supported thereupon as well asthe arrangement of the bracing timbers with respect thereto, it will beappreciated that other means are provided for lessening any possibilityof the buckling, twisting, or collapsing of the head construction withthe application of material weight or stress thereto.

Manifestly, the construction shown is capable of considerablemodification and such modification as is within the scope of my claims,I consider within the spirit of my in vention.
